Ernesto Bertarelli inherited biotech giant Serono, maker of the multiple sclerosis drug Rebif, following his father's death in 1998. With his sister Dona, he expanded the company to $2.4 billion in revenues before selling it to Merck for over $13 billion in 2007. Ernesto and Dona co-chair the Bertarelli Foundation, which focuses on marine conservation and life sciences research. The family's Waypoint Group has investments ranging from commercial real estate in London to drug companies. He also owns the superyacht Vava II.
